Mark Speight blames himself for the death of his fiancée Natasha Collins, according to a report today.

Collins was found dead at the North London flat that the couple shared on January 3.

Former SMart host Speight went missing on Monday, just days after an inquest heard that Natasha's death had been caused by an overdose of cocaine and sleeping pills.

"He didn't just blame himself for failing to save Natasha's life. He's haunted by the fact that he introduced her to cocaine in the first place," a source told the Daily Mail. "As far as he's concerned, it's all his fault - and if he could give his life to bring her back he'd do it in a heartbeat."

One friend, who spoke to Speight before his disappearance, explained: "All he wanted to talk about was Natasha and how he had let her down. He told me he was haunted by her presence all the time; that he woke up in the morning and she was there.

"He kept saying 'She didn't deserve to be involved with someone like me', which I thought was a really odd thing to say. When I told him she was a lucky girl to have been with someone who loved her so much, he just muttered: 'Everything isn't always as it seems'.

"The Mark I saw that day was a changed man, eaten up by guilt. He was beyond upset or depressed. He felt responsible for giving that poor girl drugs. Without Mark, she probably wouldn't have taken cocaine. He admitted as much to me."

Speight's best friend Stu Goldsmith recently appealed for his safe return.
